Emulex Drivers for VMware ESXi User Guide
lpfc_max_heap_size Maximum allowable memory
consumption per server for
the LPFC module.
This parameter requires a
system reboot.
Default = 128 MB
Min. = 64 MB
Max. = 512 MB
—
lpfc_max_luns The maximum number of
LUNs allowed.
This parameter requires a
system reboot.
Default = 65,535
Min. = 1
Max. = 65,535
Setting in ESXi 6.5 and 6.7 allows for sparse
LUN IDs above 256.
lpfc_max_multiq Sets how many completion
queues the driver is
requesting from ESXi for
each HBA instance.
Each completion queue uses
an MSI-X vector.
0 indicates disabled
Multi-Queue.
This parameter requires a
system reboot.
Default = 4
Min. = 0
Max. = 8
Sets the number of MultiQ FCP I/O
channels. The driver sets this parameter to
determine how many completion queues to
use per HBA port. Each completion queue
consumes an MSI-X vector and defaults to a
low number to ensure systems with large
amount of HBAs do not run out of vectors.
lpfc_max_scsicmpl_time Uses the SCSI command
completion time to control
queue depth to the device.
0 = SCSI command
completion time is not
used for controlling I/O
queue depth.
N = I/O queue depth is
controlled to limit the I/O
completion time to N ms.
This parameter is
dynamically updated.
Default = 0
Min. = 0
Max. = 60,000
—
lpfc_max_targets The maximum number of
discovered targets allowed.
This parameter requires a
system reboot.
Default = 256
Min. = 0
Max. = 4096
A driver parameter to adjust the supported
target count.
lpfc_max_vmid
Maximum number of
VMs to
be tagged. The range is 4 to
255.
This parameter requires a
system reboot.
Default = 8
Min. = 4
Max. = 255
This value indicates the numbe
r of VMIDs
supported.
lpfc_mem_tracker Turns memory tracking on or
off. Valid values are:
1 = On
0 = Off
This parameter requires a
system reboot.
0 = Disabled
(default)
1 = Enabled
Keeps track of driver heap and slab
allocation/free. It is used only when
debugging driver memory issues.
